Communication techniques connect the world with wires, cables and wire-free technology. This module gives in-depth coverage of signal propagation, multipath wireless channels, physical layer techniques including 4G, WiFi and digital broadcasting, and optical communications.
To describe and analyse the physical layer techniques used for current and proposed digital communication systems using twisted-pair cable (such as DSL broadband and gigabit Ethernet), wireless (including WiFi, 4G and broadcast systems), and optical communications, especially fibre-optic broadband
To analyse the effects of the channel in wired, wireless and optical systems, then describe the techniques used to overcome these, and the standards that have been defined for current and proposed systems
Graduate skills aims:
To develop critical skills in the selection, adaptation and application of appropriate numeric and algebraic techniques

Subject content learning outcomes
After successful completion of this module, students will:
Understand the propagation of signals along lossy transmission lines, including attenuation, dispersion, and cross-talk

'Feedback’ at a university level can be understood as any part of the learning process which is designed to guide your progress through your degree programme. We aim to help you reflect on your own learning and help you feel more clear about your progress through clarifying what is expected of you in both formative and summative assessments. A comprehensive guide to feedback and to forms of feedback is available in the Guide to Assessment Standards, Marking and Feedback. This can be found at https://www.york.ac.uk/students/studying/assessment-and-examination/guide-to-assessment/ The Department of Electronic Engineering aims to provide some form of feedback on all formative and summative assessments that are carried out during the degree programme. In general, feedback on any written work/assignments undertaken will be sufficient so as to indicate the nature of the changes needed in order to improve the work. Students are provided with their examination results within 20 working days of the end of any given examination period. The Department will also endeavour to return all coursework feedback within 20 working days of the submission deadline. The Department would normally expect to adhere to the times given, however, it is possible that exceptional circumstances may delay feedback. The Department will endeavour to keep such delays to a minimum. Please note that any marks released are subject to ratification by the Board of Examiners and Senate. Meetings at the start/end of each term provide you with an opportunity to discuss and reflect with your supervisor on your overall performance to date.
